/.i Theodore W Rap tn ATTDRN EYS Unite This invention relates to sealing strips adaptedto be positioned on the lower edge of a door to prevent rain and the like being driven through the opening between a door and a door sill, and in particular, a continuous weather strip pivotally mounted on the lower edge of a doorand adapted to be actuated to an upwardly extended position with a spring as the door is opened and also adapted to be moved downwardly to a sealing position by cam surfaces of strike plates as the door is closed.

The purpose of this invention is to provide a sealing strip for the lower edge of a door that operates automatically to close the opening as the door is closed and that moves automatically to an upwardly extended position to facilitate opening the door as the opening movement of the door is started.

' Numerous attempts have been made to provide sealing strips to prevent wind and the like driving rain under a door, however, because such devices must slide over the surface of a floor as the door is opened, it is substantially impossible to extend the sealing means below the edge of the door with the result that it is substantially impossible to prevent water being driven below the door. With this thought in mind, this invention contemplates a sealing strip that drops downwardly to definitely cover the opening at the lower edge of a door as the door closes and that instantly moves upwardly to an out of the way position as the door opens.

The object of this invention is, therefore, to provide means for actuating a sealing strip at the lower edge of a door so'that the sealing strip actuates automatically with opening and closing movements of the door.

Another object of the invention is to provide an automatically operating sealing strip for the lower edge of a door in which the device is adapted to be applied to doors now in use.

A further object of the invention is to provide operating means for a sealing strip adapted to be positioned on the lower edge of a door wherein the sealing strip is elevated with anopening movement of the door and moved downwardly-to a closed position with the closing movement of the door in which the device is of a simple and economical construction. I I With these and other objects and advantages in view, the invention embodies a tubular casing adapted to be positioned on the lower edge of a door, a sealing strip carried by and extended from the casing, brackets for r'otatably mounting the casing on a door, a spring for urging the. sealing strip upwardly with the Opening movement of the door, a strike plate for moving the sealing strip downwardly with the closing movement of the door and ashield adapted to be attached to the surface of the door and positioned to extend over the tubular casing. "Other features and advantages of the invention will appear from the following description, taken in connection with the drawing, wherein:

Referring now to the drawing, wherein like reference characters denote corresponding parts, the improved Water drip and weather strip of this invention includes a cylin drical casing 10, a shaft 11 having a head 12 on one end positioned in an end 13 of a sleeve 14 extended into' one end of the casing, a spring 15 mounted on the shaft 11, a plug 16 having a pin 17 extended from the end thereof positioned in the opposite end of the casing, a bracket 18 adapted to be mounted on the surface of adoor and having an opening 19 therein for receiving the pin 17, a bracket 2i? also adapted to be positioned on the door and having a slot 21 therein adapted to receive the head 12 of the shaft 11, an arm 22 for mounting a pin 23 on the end of the casing, a sealing strip 24 mounted on the casing and a shield, as indicated by the numeral 25, adapted to be attached to the surface of the door and positioned to extend over the casing.

The cylindrical casing 10 is provided with a continuous slot 26 having flanges 27 and 28 extended from edges thereof and the blade 24, which is preferably madeof rubber, a suitable plastic, or the like is secured between the flanges with rivets 29, as shown in Figure 3. The ends of the casing are provided with notches 30 and 31 and, as illustrated in Figure 9, the notches are positioned to receive lugs 32 on the inner surface of the arm 22 with the parts assembled and, as illustrated in Figures 4 and 5, the arm 22 may be positioned on either the rightor left-hand end of the casing. a

With the parts assembled as illustrated in Figure 4, the arm 22 is positioned on the sleeve 14 with the pin 23 extended outwardly and the sleeve 14 is positioned in the end of the casing 10 with the lugs 32 in the notches 31. The sleeve 14 is provided with a head, as indicated by the numeral 13, and the head is provided with an elongated rectangular shaped slot in which the inner portion of the head 12 of the shaft 11 is positioned, the head 12 being provided with recesses 33 and 34 that are positioned "to receive the material of the head 13 at the ends of the 3 slot. With the head 12 in position in the head .13, the material of the head 12 is peened over, as shown at point 35, to retain the shaft 11 in position in the 'sleeve14.

The spring 15 :is positioned 'on the shaft 11 with one end, as indicated by the numeral 36, extended through a slot 37 in the end of the shaft and with the opposite end 38 extended through an opening 33* in the portion of the sleeve 14 that is positioned in registering relation with the slot 26 of the casing. With the spring mounted in this manner, the end 38 urges the blade 24* upwardly to the position illustrated in Figure 3 and, upon closing a door 4%] upon which the device is mounted, the pin 23 engages :a cam surface 41 of a strike plate 42 whereby the pin rides downwardly carrying the arm 22 and blade 24 from the position shown in Figure 3 to that shown in Figure 2. The strike plate 42 is positioned in recesses 43 in the edges of an opening 44 of a door frame, as indicated by the numeral 45, and the plate is retained in position with screws, as indicated by the numeral 46.

The end of the casing in which the spring 15 and sleeve 14 are positioned, in the design shown in Figure 4, is supported in the bracket 26 with the head 12 extended through the slot 21 and the bracket is secured to the door 40 with screws 46 that extend through a flange 47 of the bracket.

The opposite end of the casing 10 is supported in the bracket 18 with pins 17 of the plug 16 positioned in the opening 19 and with the bracket secured to the face of a door with screws 48 which extend through a flange 49 thereof. The cylindrical plug or sleeve 16 is provided with a head 50 providing a peripheral flange that is positioned against the end of the tubular casing 10.

In the arrangement illustrated in Figure 5, the parts are duplicates and the arm 22 is positioned on the sleeve or plug 16 instead of on the sleeve 14 whereby the pin 23 extends into a strike plate 51, similar to the plate 42.

The shield is provided with a mounting flange 52 that is positioned against the base of the door 46 and the shield is retained in position with screws 53 that extend through the flange and into the door, as shown in Figure 2.

With the blade 24 mounted in this manner, an opening, such as may em'st at the point 54, between the door 40 and a sill 55, is covered with the blade with the door in the closed position, and as the opening movement of the door starts, the pin 23 is released from the strike plate and the spring 15 instantly elevates the blade from the position shown in Figure 2 to that shown in Figure 3 wherein the door is adapted to be opened and closed without carrying the blade across the surface of the floor.

It will be understood that modifications, within the scope of the appended claims, may be made in the design and arrangement of the parts without departing from the spirit of the invention.
